In our lab one may come across n-heptane and ethanol. They are listed below with their relevant information that was obtained from Material Safety Data Sheets.
N-HEPTANE
CAS Number: 142-82-5
Molecular Formula: C7H16
Synonyms:
heptane, dipropyl methane, and heptyl hydride
Physical Properties:
Colorless liquid with a melting point of –91 °C and a boiling point of
98 °C. This chemical is highly flammable with an autoignition temperature of 222 °C.
